A 10-megawatt lithium-ion battery energy storage system in Texas has started operations as the state’s biggest such facility to date.
Power generation business Luminant, a subsidiary of Vistra Energy, said the 42-megawatt-hour BESS is the seventh largest in the US.
The BESS is on the site of Luminant’s 180-megawatt Upton 2 Solar Power Plant in Upton Count. The battery system captures excess solar energy produced at Upton 2 during the day and can release the power in late afternoon and early evening, when Luminant said demand by system operator the Electric Reliability Council of Texas is highest.
